it looks like a piece of metal and it goes in between your throttle body and the throttle position sensor..

anywho, took my car to work and after two minutes.. CEL came back on.. car ran smooth, went and checked the code and it was just my O2 sensor as i predicted...

well, car is running good.. we'll see if anything goes worng on the way home..

AC just got fix, wooooohooooo...... ready for summer
